Title: Improvements in or relating to wave guide switches
Inventor: YOUNG LEO
IPC: H01P1/12
Filed: 1952-06-12
Abstract: 721,488. Wave-guides. DECCA RECORD CO., Ltd. June 3, 1953 [June 12, 1952], No. 14885/52. Class 40 (8). A wave-guide switch comprises a Y or T junction 10 for connecting a wave-guide to the E or H arms of magic-T's 13, 14, the left and right arms 16, 17, 19, 20 of which are shortcircuited, the two short-circuits in each magic-T being relatively alterable in position between positions in which the short-circuits are equidistant from the junction of the magic-T and positions in which they are spaced at different distances so that the fourth arm of one of the magic-T's may be coupled to or isolated from the wave-guide. In one embodiment, Fig. 2, an input arm 11 lies directly against the left and right arms 16, 17; 19, 20 of the magic-T's. The arm 11 may be continued beyond the junction with the magic-T's to form a stub closed by a short-circuit. The position of this short-circuit may be adjusted to enable the matching of the arm 11 to the magic-T's to be independent of the effective short-circuits which the magic-T's present to the arm 11' The output arms 18, 21 are coupled to or isolated from the arm 11 by inserting a metal rod 22 through holes in the arms 16, 19. In a further embodiment, Fig. 3, comprising a continuous power divider, movable short-circuit plungers or paddles are provided in the arms 16, 19. The plungers are mechanically connected at 24, and the plunger in the arm 16 is movable from a distance a to a distance a+# 4 g and the plunger in the arm 19 from a distance a - # 4 g to a distance a.

Title: Process for the manufacture of complex gold compounds of albumose-like keratin degradation products containing sulphhydryl groups
IPC: A61K38/01
Filed: 1937-06-09
Abstract: Complex water-soluble gold compounds of albumose-like keratin degradation products containing sulph-hydryl groups are obtained by acid hydrolysis of keratin substances with simultaneous or subsequent reduction and neutralization followed by reaction with a gold compound without previous evaporation.  The reduction may be effected by the presence of metals such as zinc, tin or iron in the hydrolyzing bath, by hydrolyzing with sulphurous acid or by reduction of the hydrolyzate with sulphurous acid salts.  When reduction with metals is employed the metal salts are removed by hydrogen sulphide. Aurous or auric compounds may be used to react with the keratin degradation product.  The compounds produced may contain more gold than is sufficient to combine with the sulphhydric groups present. The solutions obtained may be rendered weakly alkaline by means of oxides, hydroxides and carbonates of alkali metals, calcium and magnesium and stirred into several volumes of a water miscible solvent such as ethyl or methyl alcohol or acetone when the corresponding alkali or alkaline earth salt of the gold sulphhydryl complex separates and may be purified by reprecipitation.  Examples describe the preparation from human hair and from wool of compounds containing in the gold sulphhydryl complex sodium, magnesium, and calcium. Specifications 345,630 and 357,189 are referred to.
